Security Master APK

Security Master’s main function is the antivirus engine. It does a good job of scanning your device for malicious apps. Its Device Status Detection feature Provides solutions like anti-virus, junk cleaning, phone boosting, and CPU cooling.

Not only this it also comes with a custom browser that blocks ads while anti-phishing protection prevents you from accessing malicious URLs, keeping many web threats at bay.

With the real-time protection of the Security Master, you can automatically scan for downloads, updates, websites, and file systems, and quickly take precautions to detect security vulnerabilities.

The application, which also has an automatic security shield, can fully protect your device against possible threats. Other features are unnecessary file cleaning, memory card scanning, and call blocking.

According to TechRadar, Security Master’s default settings achieve a 96.4% protection score. However, if users turn on the Anti-heuristic detection engine, it can block 100% of threats.


Its VPN is powered by HotSpot Shield and does a fairly good job but with a limited bandwidth of 200MB which is not enough for proper usage.


Its AppLock feature enables protecting any or all of your apps with a pattern, a PIN, or a fingerprint scan. If someone tries to get in anyway but fails, you can have the Security Master take a photo of the intruder and email it to you.

It doesn’t end here the app’s built-in Wi-Fi checking aims to identify suspect wireless networks. An anti-theft alarm raises an alert if someone moves your phone, and a message security system combines notifications into one, making them easier to manage.

Booster claims to optimize your device by deleting junk files. Clearing away useless notifications, keeping your CPU cool, and extending your battery life.
